the castings on mine are just rim size and the max load. both have different castings on the back, one sais "mexico" on it
i didnt know "uni-lug" was tradmemarked. my old cragars were unilugs, but they didnt have the oval washers, the ones that these look like they need.
i never thought i made a great find, im just happy to have a couple of cool rims for $50 until i can really afford to get the salt flats.
